The vertex is the minimum or the maximum point of the parabola.
<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>
<em />
The standard form of a parabola is
The x coordinate of the parabola is calculated using:
The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:
At the end of the calculation,
x and f(x) represent the horizontal and the vertical coordinates of the vertex.
Take for instance:
The x-coordinate of the vertex is:
The y-coordinate is:
So, the vertex of is (-1,11)
See attachment for illustration of vertex of

Answer:
<em>5x-y=9, y=5x+19 write both equations in same formy=5x-9 for the first and havey=5x+19 for the second. These are two parallel lines with different intercepts. They do not intersect or coincide. No </em><em>solutions</em>
<em> </em>
<em>and y=6x+14, 12x-2y=-28 write both equations in same formy=6x+142y=12x+28 or y=6x+14. They are the same line. The solution is all of the points on the line.</em>

My choice to reflect this would be over the y axis. That would be (-1,3) for the bottom left hand corner on the original image.
